    Top shelf

    It's just a castle nut but I ordered one from another company and it was garbage. I knew it would be good quality from BMC.

    Strength is lacking

    When installing the castle nut, one of the edges where the wrench sits in snapped off. Works fine, but I'm worried that if I need to take it off that I won't be able to get it back on.
